The type of third-party responsible for receiving clicks and attributing conversions. Only applicable to iOS video campaigns. Ad sets which utilize more than one attribution source may have conversions with the OTHER value and conversions with the SKAN value.
Standard third party tracking via s2s call or clientside redirect. This represents those conversions attributed by a Mobile Measurement Partner (MMP) that is not Apple.
Conversions with this AttributionSource value were attributed by Apple's SKAdNetwork service which Tapjoy is directly integrated with.
